. `Tooll whom it may concern:

"- Be it known that I, WILnIAM HENRY DOUGLAS, a citi Y rim, to permit an exceedinglyv quick removal of the rim Vand'tire in case of accident, and replacingby a rim and tirey constructed and arranged for immediate use.

The invention consists of novel features and parts and y combinations of the same, which will be more fully de- 1 5 scribed hereinafter andthen pointed out in the claims.

` A `Vpractical. ern'bodiiiient of the invention is repre- 'sented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. 2i) Figure'l is a sideelevation of the improvement; Fig. I24 is alike view of the same showing the locking devices in an unlocked position for removal of the rim from the y spokes; 3 is an enlarged sectional plan view of the 'i improvement on the line 3*3 of Fig, l; Fig. 4 is a similarvew of the same showingfthe spokes unlocked and f .E4 partly disengaged from the sockets of the'rim, and Fig.

y 5 is a sectional side elevation of the improvementV on the f line of Fig. 3.'

. -From the hub Aoi` the.' wheel radiate in the usual manner the'; spokes B, adapted to be engaged at their outer ends by sockets C secured or formed on lthe inner face of the rim D'carrying the tire E, preferably of the v Y. inilatable'type. The sockets C are elongated in the direction'of the plane'of the'wheel' and are provided at Y.tlirr'ear' sides with openings or cut-out portions C, to

y permit of moving the rim D and the tire E secured therei on in a transverse direction relative to the hub A and l if s the spokes B,'With a view toengage the sockets with the l 5 socketsG, asl plainly indicated in Figs. 1, 3 and 5;-

When the spokes B are in the position described and I. l shown in Figs. 1, Sand 5 then one or preferably two dia- 'metrically arranged spokes'are locked in place in their f corresponding sockets, so as to vhold all the spokes 5- against the forward ends of their sockets. i

. 1 'For the purpose described the spoke to be locked in position in its socket C is engaged by the head F of a I bolt F mounted to slide in the rear wall C2 of the socket l C, and the outer endv of this boltF is pivtally connected with a link G extending'longitudinally and pivot* 55 ally connected with a lug C3v projecting 'from the for- Ward end of the next adjacentsocket `C as .Will be read` ily understood by reference to the drawings. The link G is made in sections GQ G2 pivotallyv connected with each other'by aI knuckle joint G3, which when closed 6 0 holds the link Gin longitudinal alinement with the bolt F and the head F theregi in firm engagement with the spoke B, so as to lock 'the free end in position in the for- Award end of the-socket C (see Figs. l, Sand 5). The y link G when swung into an open position, as indicated in full lines inFigs. l and-4 andin dotted lines in Fig. 5,` causes a withdrawal ofthe bolt F, so as to allow turn ing of the rirn D on the spokes B held stationary for the time being until -the free ends of the spokes B are opposite .the openings C/, then the operator vbypnlling the rim D outward in a transverse direction disengages the rim from the free ends oi the spokes B. In order l to keep the sections Gf, G2 oi the link in an extended closed position, as shown in Figs. l, 3 and 5, a spring arm H is provided, fastenedvto the section G2-and ex- 75 tending over the back of the knuckle joint G3, and the,

Vreeend of this spring arm H is adapted tobc engaged by a ring I mounted to slide on the section G. Thus when the ring I engages the springrarm H-the two sections G, G2 of the link G are securely held locked in an 80 l extended position. The springarm H is preferably provided at its free end with a head H, to prevent the -O ring I from accidentally slipping off the spring' arm,

lthe free end of whichds adapted to be pressed' inward into a groove G4 formed on the link G, to permit of 85 sliding the ringl off the arm H Whenever it is desired' to open the link G, as s hown in Figs. l and f1. The ring I is provided with a curved oiset l', to permit of read-. ily sliding the ring over the head Hf in position on the spring arm H. NOW when the several parts are in the A G to withdraw the bolt F from the free ends of the spokes B, so as to unlock'the latter in the'sockets C, after which the'operator gives a'slight turn to the rirn D, that is, until the free ends oi the spokes B are opposite the openings C. The operator now draws the v rim'forward so as to disengage the sockets from the free ends of the spokesv B. A second rimhaving an inflated" tire thereon can now be readily slipped in position asm. vthe spokes B and locked in place as above described, by closing the links G and locking the same in a closed r position by the spring arms H and rings l.V Oneof the sections Vof the link G as shown, thslsection G2, isiprvided witha turnbuckle G5 or kike means for;length.l

@. d eenen? eningr and shortening the link, to insure proper ene.z

ment of the head F oi' the holt F with the spoke B to he accident' to atirc and rirn they can be very quickly re- Y moved from the spokes and another rir'n with an inl'lated tire thereon can be placed in position on the spokes iand'securely locked thereto7 so that thev Wheel is coni-` plete to enable the vehicle to proceed on its journey.

The Wheel described is specially serviceable for use on motor cars, especially such as are used-in races, in which a quick repair oi the Wheel in ense of a bursted tire is n very essentiel requirement.l

Having thus described my invention, l claim as new and desire to secure by Letters Patent: e
